Aruar, 435 58th, Guttenberg, NJ. Filed Dec. 22, 1960, Ser. No. 77,731 2 Claims. (Cl. 131213) This invention relates to a novel and improved smoking pipe wherein the smoke is cooled and condensed by being drawn through tortuous passage means.

The primary object of the invention is the provision of an eflicient and practical smoking pipe of the kind indicated, wherein the passage means includes a first smoke cooling and condensing chamber in the stem-bit component of the pipe, a second smoke cooling and condensing chamber in the bowl component, and smoke cooling and condensing passages formed in the stem and in the bowl, which are of unusually long combined length and of novel form and arrangement, whereby greater cooling of smoke is obtained before the smoke can reach the mouth of the smoker, through the bit. 7

Another object of the invention is the provision of a smoking pipe of the character indicated above wherein the bowl component has a removable tobacco holding bowl, and the stem has at its inner end, said second smoke cooling and condensing chamber which is out of direct communication with the bore of the bit and in communication with said passage means, this chamber being closed by the bit, and the bit being removably connected to the inner end of the stem by a shank smaller in diameter than the chamber and having a bore which provides the sole communication between the bit bore and a passage of said passage means.

Other important objects and advantageous features of the invention will be apparent from the following description and the accompanying drawings, wherein, for purposes of illustration only, a specific form of the invention is set forth in detail.

In the drawings:

FIGURE 1 is a perspective view of a smoking pipe of the present invention;

FIGURE 2 is an exploded perspective view of FIG URE 1;

FIGURE 3 is an enlarged vertical longitudinal section taken on the line 3-3 of FIGURE 1;

FIGURE 4 is a horizontal section taken on the line 44 of FIGURE 3;

FIGURE 5 is a vertical transverse section taken on the line 55 of FIGURE 3; and,

FIGURE 6 is a fragmentary exploded perspective view of another smoking pipe of the present invention.

Referring in detail to the drawings, wherein like and related numerals designate like and related parts throughout the several views, and first to FIGURES 1 through 5, the smoking pipe therein shown and generally designated 19, comprises a longitudinally elongated straight cylindrical stem 12 having, on its outer end, and preferably integral therewith, a fixed lower bowl section 14, and being formed, at its inner end, with a concentric socket 16. The bottom of the socket 16 is formed with a threaded axial blind bore 18. The lower bowl section 14 is formed with an upwardly opening hemispherical recess 20, of substantial relative diameter.

The smoking pipe lit further comprises a bit 22 having a reduced cross section mouthpiece 24 and a squared outer end 26, of the same diameter as the inner end 28 of the stem 12. The bit 22 has an axial threaded blind bore 39 into which is threaded the inner end of a tubular cylindrical shank 32, the outer end of the shank 32 being threaded into the blind bore 18, with the outer end 26 of the bit engaged with the inner end 23 of the stem 12 and closing the socket to, so as to define an annular smoke cooling and condensing chamber 38, surrounding the shank 32. The shank 32 has an axial bore 34, extending therethrough, which, at its inner end, opens to an axial bore 36 extending through the bit 22.

The bore 34 of the shank 32 opens to the inner end of a straight passage A which extends longitudinally outwardly in the stem, at a slight upward and laterally outward angle, as indicated in phantom lines in FIGURE 4, and opens, at its outer end, into an annular upwardly opening groove 40, which is formed in the flat upper end 42 of the lower bowl section 14, and concentrically surrounds the hemispherical recess 2-9, The groove 40 is rendered discontinuous by a radial partition 44 which extends thereacross at a location on the longitudinal centerline of the stem 12. The passage A opens into the groove 40 at one side of the partition 44 as shown.

The stem 12 has formed therein a straight passage B which follows the path shown in FIG. 4, in the stem and opens, at its outer end, into the groove 4%, at the other side of the partition 44. At its inner end, the pass-age B opens through the bottom of the socket 16 at a location spaced above and in line with the shank 32. A straight passage C is formed in the stem 12, below the passage A, which is centered in the stem and inclines outwardly and upwardly, relative to the centerline of the stern, and opens, at its outer end, through the inner side of the recess 20, at a. point near to the bottom of the recess 20. The passage C opens, at its inner end, through the bottom of the socket 16, at a point spaced below and in line with the shank 32 and the inner end of the passage B.

The sidewall of the recess 20 of the lower bowl section 14 is threaded, at its upper end, as indicated at 46, to receive a reduced diameter boss 48 on the lower end of an upper tobacco-receiving bowl section 50, whose lower end 52 is of substantially the same diameter, and bears upon the upper end 42 of the lower bowl section 14, so as to close the groove 44, and close the upper end of the recess 29, so as to define a smoke cooling and condensing chamber 54. The chamber 54 is not in direct communication with the groove 44.

The upper bowl section 5% has an upwardly opening tobacco receiving socket 56 which has a fiat bottom surface 58 which is parallel with the flat undersurface 6d of the boss 4%. Restricted communication between the chamber 54 and the interior of the bowl pocket 56 is provided by restricted opening means which, in the case of the form of the invention shown in FIGURES 1 through 5, takes the form of preferably three equally circumferentially spaced holes 62, through the boss 43.

In the case of the form of the invention shown in FIGURE 6, and generally designated 16 the restricted opening means takes the form of a centered axial, cylindrical pin 64 which rises from the bottom of the recess 20, and a single centered hole 62 through the boss 48*. The hole 48 is larger in diameter than the pin 64 so that an annular restricted opening is defined around the pin.

In use and operation, with the upper bowl section socket 56 containing burning tobacco (not shown), a suction applied to the mouthpieces and its bore 36, draws smoke from the bowl socket 56 through the restricted openings 62 or 62 into the bowl chamber 54, whence the smoke is drawn through the stem passage C into the stem chamber 38, into the passage B to and around the groove 40, and to the bit bore 36, through the passage A. This long and tortuous path of the smoke from the bowl socket 56 to the bit bore 36, assures maximum cooling of the smoke before it reaches the mouth of the smoker. Further, the dwell of the smoke in the chambers 54 and 38 assures maximum condensing out and collection of noxious wet material entrained in the smoke. The chambers 54 and 38 and the groove 40 are readily accessible for cleansing, and the passages A, B, and C can be readily cleaned with ordinary pipe cleaners, when the upper bowl section 50 and the bit 22 are disconnected.

Although there have been shown and described herein preferred forms of the invention, it is to be understood that the invention is not necessarily confined thereto, and that any change or changes in the structure of and in the relative arrangements of components thereof are contemplated as being within the scope of the invention as defined by the claims appended hereto.
